Referring to the drawing, I have indicated my invention applied to ra conventional table' and the detachable top `constructed in accordance;A with this inventionisy indicated at 10 and has the usual edgesor flanges'll.iv

- I'Ihe undersurface of thetop is preferablyprovided with some non-abradant material, as-fforv example, a layer-of felt 12 which is adhesively" united to the. base 1,3 o f .the tgp.

The-base 113 *of the Jtop 'fis'preferably formed of a fibrous material such as Wood fiber, paper pulp, corn stalks, cane stalks, or any composition embodying two or more of the foregoing. I mayalso employ a product made by the Masonite company and called Pressdwood which is a fibrous material.

The base 13 possesses the characteristics of ilexibility'and plasticity and is moisture repellant. Furthermore, it is insulating and substantially inert with respect to extremes of 'heat and cold so that it will be temperature resistant for all ordinary purposes. This material is further characterized by great tensile strength and is resistant to abrasion. In addition, the 5 brous material which I employ is substantially free of volatiles? Withinfanermal' range oftern-y perature's", so f that nov perceptiblel kor objection-l` ableodors'will'be'created y 'f As stated, the base 13 ismoisture' repellant,z

ythateis to say, it `may "befinherently water vproof or some suitable `water-proofing 'agent 'may be" employed. This vWater proofing' agent Willpreferably have 'fa'ghigh -point Aof volatilization so that'underiio circumstances will any objection' ableodors be created;V l

The base 13,5in"addition to its'flexible"an'djy plastic properties, is, however, sufficientlyv rigid to'enable itytobe satisfactorily Worked, thatfis to sayf'cut into strips and suitably miteredor beveled, 'brits Acontour arranged as'lequired. f 153': v

Thus, j with? variousn articles, to which thef` top is applied, the contour assumes a varietyfof shapes and this can be easily cared for with ther present invention ,by sawing or"compressing the' r'naterialfto the desired configuration.

lFor the `lpurposeyof the priming, material, I employ lacquer, paint, enamel, or varnishvvliichy maybe eitherfan' oil'basefor what is termed in thetradegai,synthetic resinous'enamel. such 30` y''ateifialwill be 'substantially water yproof,plaais-F'i L,"It v.v {l'illfal-so havethe characteristicpfQbeing abrasionresistant, and which, ias stated, will not vmt'iliz'at 'norman temperatures and'm any' 35' event ,vyill Vpossess n'o objectionable odor.

Coatings of this character are available which are alkaline, acid, and neutral, Aand. I preferably employ one Which will be substantially acidand alkali resistant, according to the use to which the product must conform. In preparing rthe coating, the synthetic resin isi dissolved by a solvent of either the ethyl, butyl, or methyl 50 family, depending upon whether the material is to be used for air drying or oven baking and the quickness with which the varnishmust dry.

I preferably employ also in the coating, a plasticizer to permit the coating to expand and conwhere a hcolor, tint,or,hue is emp1oyed, the pigments orzif tlfleriig'ledehts for *alle ground't finness, nixed with a; rduired percentage of nitro-cellulose, whereupon the miic ture is reduced -to the proper viscosity by addl""" tion'of a suitable solvent'. or carrier sucitffa's ethyl acetate. .Y x

Incarrying out the irivujo'n, theli after appropriate sanding ts'rfothnss; l''s applied to it a priming coat, whose principal ingredient is one of the matrialbabv and preferably a synthetic resin of the,polybasi c i 1 yalkali proof and will reactfrwith the,material'of tliebase to strengthenthe same'. to'V produce a ver-` Vv"sirfor'iglacl esion. without,N however,v raising graifof theVK matrialofythe base,
